Title: Method of emptying a furnace ash pit - uses reciprocal frame with pivotal pusher shutters controlled by stops
IPC: F23J1/02
Filed: 1974-04-19
Abstract: The ashes fall into a pit which contains a frame formed by two beams (2, 3) either circular or rectangular in section. The beams are joined at the ends. The frame is capable of a reciprocating motion operated by a ram, and is supported on bearing rollers. A number of pairs of shutters (12, 13) close the space between the beams and pivot about vertical axes. Movement of the frame in one direction causes the shutters to close against stops and the ash is pushed off the end of the box for further handling. On the return stroke the shutters are opened so the frame moves without taking the ash with it. The shutters are opened so the frame moves without taking the ash with it. The shutters are controlled by upper arms (16) which have stops (19) engaging pairs of fixed stops (14) at the ends of frame travel.

Title: Safety wheel for tubed tyres - with sealed rim and sealed valve housing to contain leaks in tyre cover
IPC: B60C23/04
Filed: 1974-05-03
Abstract: The safety wheel has a wheel rim made from one or more parts, joined together to form an airtight seal. The tyre cover is sealed on the rim to form an airtight cover for the inner tube. The valve of the inner tube is fed through a special housing attached to the wheel rim by special sealing rings so that the space between the tube and the cover is airtight. The side of the valve housing has an extension fitted with a membrane. When air leaks from the inner tube to the space between the tube and the cover, the membrane is pressed outwards and operates a leak indicator.

Title: Spring-balanced weight compensating mechanism - for column-mounted drawing boards has spring holding member with inner and outer threaded adjusting nut
IPC: A47B27/06
Filed: 1974-09-10
Abstract: The helical balance screws which compensate for the weights of the drawing board are clamped to a movable part of the apparatus and to a fixed stand by holding members, of which at least one has the inner and outer threaded adjustment nut, so that the inner thread engages with a screw spindle and the outer thread engages with the pitch of the spring. The length of the spiral springs, which is effective for compensating the weight, can be adjusted by simply turning the adjusting nut outside the drawing board apparatus, so that the spring characteristic of the compensating spring can be adjusted infinitely and adapted to different weights.

Title: Low density high strength alkali silicate material - for use in insulating buildings
Inventor: SLEGHEM MICHEL
IPC: C04B28/26
Filed: 1975-04-29
Abstract: A low-density high strength expanded alkali metal silicate building material is produced by homogeneously mixing an aq. soln. of an alkali metal silicate with a pore-producing agent comprising a mixt. of finely divided Al and Si, and with a finely divided active charge, pouring the mixt. into a perforated mould larger than the volume of the mixt. to allow its expansion and removal of heat and steam produced by the reaction and separating the mould from the product which has been dried by the heat evolved. A low-density high strength material with a practically uniform pore size is obtd. without requiring external heating. The material can be used to insulate buildings by an 'in situ' process.

IPC: B01D17/02
Filed: 1975-06-19
Abstract: In the sepn. of light liqs. from water, partic. oil-bearing effluent, by passing the water in known manner through >1 non-vertical flow channel delimited at its upper side by a wall and by discharging the light liq. floating up to and flowing along the underside of each such wall, the improvement whereby the discharge of the liq. along the major part of each wall delimiting the flow channel takes place by passing through the underside thereof, pref. through openings therein or by absorption in an absorbent matl. which can be renewed as required. Method is partic, useful where relatively small amts. of light liq. e.g., oils, benzene etc. are to be removed e.t., from an effluent leaving a first or rough separator. The effluent residence time is reduced compared to that normally required. The absorbent matl. pref. absorbs oils, benzene etc., selectively and may be an expanded perlite the surface of which has been made hydrophobic or oleophilic e.g., with bitumen.

Title: Tyreere valve with leak indicator - attached to side of valve and linked to space between tube and tyre
IPC: B60C29/02
Filed: 1975-06-24
Abstract: The tyre valve is fitted through the wheel rim and is attached to a tube inside the tyre. The valve body is provided with a special bore along one side, linking a lateral port with the space between the valve seat and the outside of the tube. A pressure indicator (6) is screwed into the lateral port and is operated by increases in pressure between the tyre and the tube. This gives an early indication of any leaks in the tube, and enables the driver to take corrective action before the vehicle becomes dangerous to drive. The pressure indicator comprises a simple membrane operated indicator plug.

Title: Expanding dowel for attaching objects to thin walls - has longitudinal slots to permit radial deformation when dowel bows outward
IPC: F16B13/14
Filed: 1976-11-23
Abstract: To attach objects to thin partitions (4) forming part of a cavity wall (5, 6) a dowel (2) of flexible plastic is used. The dowel has a moulded on metal nut (3) with a screw thread to suit the fixing bolt (1). The dowell has four equally spaced longitudinal slots which allow the material (11) between the slots to bow outwards when the bolt engages the nut. The material thus forms a collar which retains the dowel in the hole in the partition (4). This form of plug is particularly useful if the partition or wall is made of brittle material. An alternative form of dowel has a stud instead of the nut and bolt and a nut screwed onto the stud in place of the bolt head.
